“We like the flexibility of opening spaces fast and closing them fast if we find the location is not right,” FitHouse founder and Chief Executive Clement Benoit, 33, told The Post.

FitHouse invests up to $150,000 in each of its new spaces.

A serial entrepreneur who launched a restaurant-delivery company at age 21 in France and a logistics company, GeoPost, that was sold last year to French Groupe La Poste, Benoit claims that FitHouse “has the most agile approach to scalability in the fitness industry.”

As part of its strategy, FitHouse will look to replace shuttered studios in popular neighborhoods, Benoit added.

The company is also aggressively poaching instructors across the city, dangling higher pay — $100 to $150 per hour — compared with the $75 to $90 pay at comparable studios, according to Benoit.

To fuel its expansion, Benoit has already raised $3 million in venture capital led by Global Founders Capital, including Xavier Niel and Fabrice Grinda.
